[SDL] Keys LEFT UP and SPACE

[Alan Wolfe]

Here's a good article on this.

Whenever this issue comes up I just google for "keyboards are evil".

Good info (:

Team-
Different keyboards can handle more or fewer key presses at the same time.
Get a new keyboard and odds are your keyboard issue will be gone. Some new
keyboards do exacyly what you are talking about but it's rare. Make it so it
displays all of the keys on the screen like "up button is pressed" and such
and this will show you. Switch keyboards a few times and note the
difference. The overlap/overflow happens just like you say at one point or
another according to the order of the scan codes.
